Vulnerability Details

Class:       Unauthorized Access
Versions:    2.23.3 and above.

Description: Bugzilla::WebService::User::offer_account_by_email does
not check the "createemailregexp" parameter, and thus
allows users to create accounts who would normally be
denied account creation.
The "emailregexp" parameter is still checked.
If you do not have the SOAP::Lite Perl module installed on
your Bugzilla system, your system is not vulnerable
(because the Bugzilla WebService will not be enabled).
